O Nmap - “Network Mapper” é uma ferramenta de código aberto para exploração de rede e auditoria de segurança.
Ela foi desenvolvida para escanear rapidamente redes amplas, embora também funcione muito bem contra hosts
individuais.
O Nmap utiliza pacotes IP em estado bruto, de maneira inovadora para determinar quais hosts estão disponíveis na rede,
quais serviços os hosts oferecem, quais sistemas operacionais eles estão executando, que tipos de filtro de pacotes/firewalls
estão em uso, etc.
Embora o Nmap seja normalmente utilizado para auditorias de segurança, muitos administradores de sistemas e rede
consideram-no útil para tarefas rotineiras tais como:
• Inventário de rede.
• Gerenciamento de serviços de atualização agendados. • Monitoramento de host ou disponibilidade de serviço.
Comando mestre para o inicio do “Network Scan/Map”, o campo do endereço de rede também determinando a mascara
de rede neste caso o /24.
